Grapher is a utility present in OSX that helps us to create graphs of equations in 2D and 3D. It is an excellent tool for exploring mathematics and for performing analytical tasks.
With Grapher, you can evaluate an equation at a specific point, find the point where two equations intersect, and calculate the common values of an integral equation.
It is an application that is included by default in OS X, it is found in Launchpad / “OTHERS” folder and what it allows is to make graphs, in 2D and 3D, from equations, derive and integrate the curves, calculate areas, find tangents, maxima, minima, inflection points, ... And all this in a very simple way. For example, if we write y = 2x2, it will draw a parabola, if we are to Equation / Integrate, will calculate its integral, showing us the equation of the integral. If now we will Equation / Integration… Will calculate the area between the curve and the OX axis, in the interval that we indicate, then shading the calculated area. The integration allows it to be done by the methods of Romberg, Owl: Runge kutta of order 4, being able to indicate the number of iterations, the order, ... with which quite good results can be achieved. The minimums / maximums are calculated in Equation / Find Root.
If you want to see examples that help you know how to handle this great utility, it also offers us a wide range within the utility itself. So, if you are a student or teacher and you have to make use of a program to be able to draw graphs and interact with them, you will surely not ignore this post since you finish reading it.
